GREENLAND: Two new studies suggest that meltwater from the Greenland ice sheet has not slowed down ocean circulation in the North Atlantic and may not be behind the ominous cold patch of ocean called the ‘cold blob’.

Wire fences and walls along country boarders are a huge problem for wildlife. Animals die after getting entangled in the wires and many species are cut off from important seasonal habitats. This situation forces a re-think of conservation strategies across borders, says researcher.
